Abstract: 23,086. Hardy, J. F. Oct. 19. [Cognate Application, 9199/12.] Sale apparatus.-The apparatus is flat and compact so as to adapt it for attachment to seats in theatres, the walls and tables of restaurants, &c., and is of the type in which a series of inserted coins acts as a pusher to eject the package to be vended. Casings.-The rear plate B of the casing is attached to the seat, and a flange B<2>, Fig. 7, of the plate has a lug B<5> which enters a slot in a flange A<5> of the front plate A; a spring A<13> engages the flange B<2> and must be pressed back by a special key G, Fig. 4, which is passed through the coin slot A<10> and a curved slot A<14> in a plate A<32>, before the front plate can be removed. Delivery mechanism; coin action, mechanicalconnexion.-The coin is inserted by a slot A<10> in the front or side of the machine and a slide E is pulled out, whereupon the coin passes into a runway between the front plate A and a plate A<6>, Figs. 4 and 5. In this position, it rests on an arm C<3> of a pusher C, which is guided in a slot A<8> in the plate A<6> and has an arm C' engaging the topmost packet, or on the top of the last coin inserted. On pressing in the slide E, it engages the topmost coin and moves down. the coins F, the pusher C, and the column of goods D, the bottom packet escaping past springs A<11> and falling to the delivery tray A<4>. To prevent thin coins from sliding past one another, spring fingers A<18> are formed on the plate A<6>, the ends of the fingers pressing against the centres of the coins. These fingers may be provided with depressions or corrugations A<19>, or the tips of the fingers may be bent down, and the resiliency of the fingers may be gradually increased towards the bottom of the plate by making them of gradually increasing length. Diverting improper coins.-The lower edge of the pusher E is of semi-elliptical form so that a correct coin is engaged by the tips near an horizontal diameter. The central portion of the edge is bevelled at E<2> and provided with projections E<3>, E<4>. A small coin is engaged by the projection E<4> and is pushed by the bevelled edge E<2> through an opening A<7> in the plate A<6> into the rear part of the apparatus. In order to hold thin or worn coins securely, the engaging tips of the pusher are bevelled in the reverse direction to the portion E<2>. In the arrangement shown in Fig. 9, a magnet H is mounted in the front plate and the slide E is provided with a lateral coin pocket E', into which the coin is inserted when the slide is in the depressed position, the slide then being raised to enable the coin to pass by an opening A<22> to the coin runway. Iron disks are attracted and held by the magnet, and when the slide is depressed are swept off by a projection E<11> which works in grooves H<2> in the poles of the magnet. Coin-slit closing devices.-During the delivery of the last packet, the member C engages a flange A<3> and prevents the complete inward movement of the slide E. A sliding indicator I, pushed out bv the coins as they pass down the runway; enables the attendant to ascertain when half the packets have been sold without opening the machine.
